Airsal 80ccm cylinder for 139sqm
Today I found some time to measure the compression ratio of the Airsal 80cc cylinder for 139 square meters. I was really amazed! With an original 50ccm cylinder head (Euro2, combustion chamber volume 4,8ccm), the Airsal has a compression ratio of fabulous 15,5: 1 (!!!). I was excited about the test run.
